Description
Adjustable bolt-down post base (with plate) 0–125 mm – 3 mm plate, gold zinc-plated
The adjustable bolt-down post base with plate is a structural steel connector designed for fixing timber posts to concrete foundations. Thanks to its continuously variable width adjustment, it allows precise fitting to different timber cross-sections, eliminating the need for multiple size variants on a single construction site.

The post base consists of a base plate fixed to the substrate, a threaded spindle and two movable side plates that slide along the guides and allow smooth adjustment of the spacing. The robust plate thickness provides adequate rigidity and load-bearing capacity of the connection, even under the full load of the post.
The post base holds the post at a safe distance from the ground, effectively protecting the end grain of the timber from capillary rise of moisture from the concrete. The gold galvanised finish gives the component an attractive appearance and an additional layer of corrosion protection — a solution that is particularly useful in visible structures such as pergolas, shelters and decks. The mounting holes in the base plate and side plates allow a secure bolted connection to both the foundation and the timber post.
Design features
- Stepless adjustment — one post base accommodates many post cross-sections
- Moisture protection — post raised off the concrete, no capillary contact
- Threaded spindle joining the base plate and side plates into a rigid unit
- Guides with slotted holes allowing precise positioning of the plates
- Gold galvanised finish blending with the natural colour of timber
- Mounting holes in the base plate and side plates for bolted connections
- Compact form making storage and transport to the construction site easier
Applications
- Pergolas and shelters — fixing timber posts to foundation footings
- Decks and garden gazebos — mounting the load-bearing structure raised off the concrete
- Timber fences — durable fixing of posts to the plinth
- Frame structures — connecting posts to pad foundations
- Canopies and carports — professional timber-to-concrete connection with adjustment
The post base is sold as a single piece, allowing you to order the exact number of components needed for your project. The compact parcel size makes storage and transport easier, even for larger orders. The gold galvanised finish blends harmoniously with the natural colour of timber, so the connector does not need additional concealing in decorative structures.
